6 . initial orbit determination for satellites based on angle measurements is investigated 對繭于純角度觀測倩息的衛(wèi)星軌邀確定方法進(jìn)行了研究。
We have adopted the simplified methodology for pattern function to obtain the results of the initial orbits of each hydropower station . further more, the final results of best operation trace and capacities process concerning each hydropower station have been obtained through the relevant information iteration and information transmission 對模型函數(shù)采用簡化運用策略求得各電站的初始軌跡,通過關(guān)聯(lián)信息迭代并借助信息傳遞,最后得到各電站的相應(yīng)最優(yōu)運行軌跡和相應(yīng)出力過程。
During simulating the observation of the synchronous debris, choicing two sites : nanjing observatory and kunming observatory, employing two ways that are tracking stars and tracking satellites, and observing the geostation-ary satellites of the identical geographical longitude are in this paper . the method of finding the new object and its initial orbit are given, too 在對于高軌空間碎片進(jìn)行了觀測模擬時,分別選取南京和云南兩個觀測站;采用兩種跟蹤方式:跟蹤恒星和跟蹤衛(wèi)星;并對于同一地理經(jīng)度上的同步衛(wèi)星進(jìn)行觀測;提供了發(fā)現(xiàn)新目標(biāo)的方法;并給出了新目標(biāo)的初軌多種計算方法。
